CORNER-SHIELD FOR BUILDNG-SIDING.

Specification of Letters Patent.

Patented Mar. 5, 1918.

Application led July 28, 1916. Serial No. 111,853.

To all whom it may concern.'

Be it known that I, THOMAS E. ADAMS, a citizen of the United States ofAmerica, and resident of Beatrice, county of Gage, and State ofNebraska, have invented certain new and useful Improvements in andRelating to Corner-Shields for Building- Siding, of which the followingis a specilication.

T his invention relates to certain improvements in corner shields forbuilding siding; and the objects and nature of the invention will bereadily understood by those skilled in the art in the light of thefollowing explanation of the accompanying drawings illustrating what Inow believe to be the preferred embodiment and mechanical expression ofmy invention from among other formations and constructions within thespirit and scope thereof.

rlhe corner shield of my invention is characterized by nail head guardscomposed of annular ribs or bosses pressed in the sheet metal oftheshield and forming cup-like depressions through which the nail holes orperforations are centrally arranged and in which the nail heads arelocated after the shield is secured in place on the siding; this nailhead guard formation being designed to provide approximately smooth orrounded surfaces surrounding the nail heads and over which paint brushbristles can freely pass and by which said bristles will be deflectedfrom the nail heads to prevent said heads gathering surplus quantitiesof paint from the bristles and the consequent objectionable appearanceof the resulting painted surface, and to cause any surplus paint togather in the depressions around the nail heads.

rl`he shield of my invention is also chai'- acterized by a peculiarupper end formation which not only stiffens the shield against spreadingor opening but also renders the shield applicable to drop siding.

The shield of my invention is also char-V acterized by peculiarformations rendering it capable of use in finishing the corners of dropsiding and avoiding the necessity of employing the objectionable dropsiding corner joints now commonly followed where drop sidings are used.

Vith these and other objects in view the invention consists in certainnovel features in construction and formation as more fully andparticularly set forth and pointed out hereinafter.

Referring to the accompanying drawings Figure l, is a perspective viewof a portion of a drop siding corner equipped with shields constructedin accordance with my invention.

Fig. 2, is a vertical sectional view on the lines 2 2, Fig. l.

In the drawings, l show a corner stud 1, and drop siding boards 2,lapping the outer side faces of said stud and approximately meeting attheir ends to form the siding corner. These boards are of the commonformation with longitudinal grooves in their bottom edges, andlongitudinal tongues at their upper edges. The opposite side faces ofeach board are fiat and parallel except where beveled off or rabbeted(see 2a) at the upper portions of their front faces.

Heretofore, the corners of buildings provided with drop siding have beenfinished by vertical corner boards or strips traversing and nailed tothe ends of the approximately meeting siding boards but this old cornerfinish has always been objectionable for various reasons among which canbe noted the fact that the corner strips leave spaces between the outersurfaces of the beveledV portions 2a, of the siding-boards and the innersurfaces of the corner strips which spaces are not accessible forpainting.

I provide a sheet metal corner shield to lap and approximately closelylit and cover the outer surfaces of the end portions of a pair of dropsiding boards at the corner of a building and to cover and bridge thejoint between the end edges of said boards, and to hence avoid thenecessity of employing said vertical corner strips.

In the particular example illustrated, each metal corner shield issuitably formed from a single sheet metal blank to provide a pair ofsimilar vertical wings 5, diverging approximately at right angles fromthe central longitudinal or vertical corner angle or bending line 6 withthe lower edge portion of the blank bent inwardly to form a bottomhorizontal inturned flange 7, extending throughout the length of eachwing 5 with the intermediate portion of the iiange below the angle 6,preferably formed with a tuck 8 indicated by dotted lines to stilfen thestructure. This tuck formation at the junction between the divergingportions of the flange is not claimed herein and hence is not fullyillustrated, and described hereby.

Each wing of the shield is approximately fiat and vertical so that theshield will snugly fit the flat vertical outer faces of the two boardsengaged thereby, and the upper end portions 9 of the two wings aredepressed or curved inwardly and upwardly to conform to and snugly fitthe beveled surfaces 2a, of the upper portions of the boards and toprovide the fiat vertical top edge portions or tongues 10, fitting theouter side faces of the top edge portions of the boards including theirtop edge tongues. The shield is hence formedv to extend approximatelythroughout the full vertical widths of the boards engaged thereby, withits bottom ange fitting the bottom edges of the two boards and with itsupper end tongues 10 extending with the tongues of said boards into thebottom edge grooves of the next set of boards above.

The depressed upper end portions 9, of the two wings 5, of the shieldare joined by a longitudinal corner rib 11, that constitutesapproximately a vertical continuation'of the angle or bending line 6 ofthe main body of the shield and that terminates at its upper end in ashoulder 19. adapted to approximately engage the continuous fiange 7 ofthe next corner shield above. This vertical rib 11 terminates short ofthe upper end tongues 10 of the shield, or in other words, does notextend to the top edge of the shield. The flat blank from which theshield is formed has a central U-shaped notch cut in its upper end, sothat in shaping the shield, the portion of metal between the depressedportions 11, can be gathered or pressed up to form the stiffening rib11, and the inner corners of the tongues 10 can be approximately broughtinto contact above the depressed' shoulder 12, that forms the upper endof said rib.

By this peculiar rib formation, the upper portions of the wings of theshield are braced and stifened against opening or bending outwardly, thecorner between the portions 9, is closed against passage of moisture, anattractive finish is attained, and the depressed upper end of the ribnot only forms a stop against undue upward adjustment of the shield butsaid upper end is so located below the iiange of the shield above as toprevent water dripping into the upper end of the rib from the shieldsabove.

The shields are secured to the siding by nails 15 which are alsopreferably utilized to secure the-ends of the siding boards to thecorner stud 1. Each shield is formed with nail holes arranged in theouter edge portions of its wings, preferably below the depressed upperends 9. 1n the particular example illustrated, each jwing is shownformed with two nail holes in its main or body portion. Each nail holeis formed at the center of the floor or bottom of a cuplike depression16, surrounded and in fact formed by a surrounding annular boss, rib orelevation 17, pressed up from the sheet metal of the shield. After theshields are applied, the heads of the nails 15 are located down indepressions 16 and are surrounded and guarded by the deflecting ribs 17which are designed and formed to deflectpaint brush bristles from thenail heads and to prevent the nail heads scraping or collecting surplusquantities of paint from paint brushes during the operation of paintingthe shields and siding. Heretofore, one objection against the use ofmetal corner shields in house construction, has been based on theunsightly appearance of such shields after the house siding has beenpainted caused by the dried heavy streaks of paint extending down on thesurfaces of the shields from each nail head. These streaks are formed bythe surplus paint collected from the paint brushes by the heads of thenails securing the shields. This surplus paint is not absorbed by themetal surfaces of the shields but travels down from the nail heads anddries.

r1`he ribs 17 of my invention are formed to prevent such engagement ofthe nail heads with the brushes as will cause this surplus deposit ofpaint, while the depressions 16 in which the heads are countersunk willretain paint around said heads and seal the nail holes.

rlhe shields can be applied to the corner of a previously completedsiding, by forcing the tongues 10, of each shield upwardly along thetongues of the pair of boards to be covered and into the bottom groovesof the pair of boards immediately above, by hammer or other blowsapplied to the lower end of the shield (at 8) until the tongues 10, aredriven home. The shield can then be pressed in against the faces of thepair of boards with the flange 7 fitting the lower edges thereof,whereupon the nails 15 can be applied. The shields can also be appliedto the boards as the siding is built up so that the nails 15 can beutilized to secure the ends of the board to the corner stud.

It is evident that various changes and modifications might be resortedto without departing from the spirit and scope of my invention and hence1 do not wish to limit all features thereof to the exact disclosureshereof.

TvVhat 1 claim is 1. A metal corner shield for drop siding composed of apair of diverging wings to fit the front flat faces of a pair of sidingboards and having depressed upper ends to fit the beveled upper frontportions of said boards, said shield formed with a longitudinal cornerstiffening rib between and joining` the depressed upper portions of saidwings, substantially as described.

2. A Inet-al corner shield composed of a pair of diverging wings formedto fit and cover the outer sides of the ends of a pair of siding boards,the upper portions of said wings being depressed and formed withupwardly projecting flat tongues, said shield being formed with alongitudinal rib between and joining the depressed portions of the wingsbelow said tongues, the upper end of said rib forming a depressedshoulder.

3. A metal corner shield composed of diverging wingsv formed to closelyfit and cover the outer surfaces of a pair of siding boards and tobridge the angle between the same, said shield formed with an outwardlyprojectinglongitudinal stiffening rib at the angle between said wings,the upper end of the rib forming a shoulder.
